I made a debugger that draws the state machine of the program

Re: I made a debugger that draws the state machine of the program
#52I would love to have a visual representation of all the possible branches that can be taken in a body of C code, with an easy way to ask the program to tell me what are all the conditions that must be met for this branch to execute.
Re: I made a debugger that draws the state machine of the program
#53That is absolutely awesome. I used to have something like this: a pair of very fast dacs hooked up to the 16 address lines of my computer and another dac hooked up to the databus. It allowed me to look straight into the memory of the machine as the processor was accessing it, quite a powerful tool. Yours is nicer though (and with todays memory size I'd hate to think about the quantity of data that passes in a split s…
> a pair of very fast dacs hooked up to the 16 address lines of my computer and another dac hooked up to the databus. Here's an article about it, with photos [1]. I remember reading it in BYTE, years ago. https://archive.org/stream/byte-magazine-1978-02/1978_02_BYT... Edit: I'll bet it's no longer possible to do this on modern CPUs; either the memory busses are inaccessible (SoC) or so highly optimised (DDR4) that it…
Bunnie Huang used an FPGA on a pretty fast bus to extract the XBox's ROM. Granted, that's no longer a "modern" CPU, but still interesting.
See the "Update on ROM extraction and decryption" section here: http://www.xenatera.com/bunnie/proj/anatak/xboxmod.html

Yeah that was the idea, I'm posting it around to see if I can get a few folks interested in porting it to different languages. Maintaining everything is hard on a one man teenage team.

That reminds me of the old story of people having a audio speaker connected to the address but of their mainframe so they could detect error conditions by the sounds being made.
As I recall, it was a radio that was tuned to the Kilohertz band. This was before the FCC was so careful about computers emitting radio waves. A computer that has a clock cycle measured in Kilohertz can emit radio waves in the Kilohertz band. This makes "music" of a sort, especially when the program running does many things repetitiously. In the early days of computing, multiplication was implemented as repeated addi…
I always thought that a something like this was how the computers on Star Trek worked.
"Computer! Run a level five diagnostic of the starboard nacelles!" bloop bloop bloop...
The foley artists did a pretty terrific job of using sound to differentiate between heavy computation, success, and failure etc. Makes me kinda wish my computer could play a minor third instead of just plopping up a dialog box when things go wrong.

I'm slightly saddened that Github doesn't recognize Brainfuck files.
Of course it does: https://github.com/r0nk/ward/blob/master/hello.bf https://github.com/github/linguist/blob/master/lib/linguist/... Just not in Ace (their code editor). It doesn't count it in language statistics, though.
Probably does but falls under a threshold.

Hmm, this looks like a different issue. Brainfuck is recognized in the stats, if you head to search: https://github.com/r0nk/ward/search?l=makefile
It's not showing up in the color bar, though. Loggin' dat issue.
Re: I made a debugger that draws the state machine of the program
#58All right, I'll be the first one to admit that I don't know what the hell I'm looking at. Would some sort of explanation, or at the very least some source code, be too much to ask?

Been pondering something like that for networking. A while back i read about a guy who had set up his phone so that it would play certain tones when it detected APs while walking around town. This based on their signal strenght, security settings etc. This got me thinking back to my analog modem days, and how i could tell if i was getting a good connection or not depending on the noise it would make during the handsh…
For those who don't know: Ping makes a ping sound on linux. You can choose ping on success or ping on timeout (or silent.) Fantastic for live work.
Don't find anything about that in the docs for Gnu ping...

There used to be an IDE called "Together" that supported bi-directional transformation between source code and diagrams. Although it sounded like a really cool idea, it didn't take off. Seems text is best (maybe because it supports incompatible hierarchies better).
Thanks for the info, I'd never heard of that IDE before. With its common name it's been impossible to find screenshots so far. > Although it sounded like a really cool idea, it didn't take off. That could have been because it was bought by Boreland, who had a history of 'not succeeding' with projects, whose focus was elsewhere, who lost key staff at an important point, and then were bought out and mismanaged from the…
It still exist and Borland has ridiculous small screenshots on their website
